The track will be recorded today and Friday at Whitfield Studios in London, with further recording taking place next week in Los Angeles.

All proceeds from the single will go to Save The Children.

Sharon said she was particularly moved by the tsunami tragedy because the Osbourne family had been due to take a holiday in the affected area.

"The whole of my family were supposed to go to Thailand three days after the disaster happened. This is why I personally feel so connected to the tragedy," she said.

"It just goes to prove how uncontrollable nature is and the tragedy it can bring.

"My heart goes out to every person affected by this tragedy and that is why I am putting this together in the hope of raising more funds to help these people rebuild their lives, especially the children.

"Everyone has come together for this project and offered their time and full commitment without question."

No release date has been confirmed for the record.

Tears In Heaven was originally recorded by Eric Clapton as a tribute to his four-year-old son Conor, who died in 1991 by falling from the window of the star's New York apartment.
